Cerahelix, headquartered in Maine, USA, develops and manufactures energy saving filtration products using DNA biotechnology combined with ceramic materials.

DNA is used as a template to create up to 10x smaller pore sizes in ceramic membranes than previously possible. The combination of high purity with high durability and a sharp molecular weight cutoff helps the PicoHelix reduce energy use by more than 90% compared to thermal separation methods. Combined, these features make PicoHelix membranes a highly attractive option across a wide range of applications where ceramic membranes previously could not be used in industries including industrial water-reuse, organic solvent separations and concentration of bio-based chemicals and pharmaceuticals.
